Tiger Alleged Mistress #3 -- Saved by the Bell

Tiger Woods' alleged third mistress, Kalika Moquin, hasn't been spotted since her name surfaced as being one of Tiger's "transgressions" -- but she popped up this week at a Califonia karaoke bar ... with Mr. Belding.

Kalika Moquin

Belding -- or Dennis Haskins to anyone over the age of 40 -- is a frequenter of Dimples in Burbank and is a staple in Las Vegas ... where Kalika happens to work as a nightclub executive.

At least she's not hanging with Screech.
